Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hello,
I just received my Thingy:91X which I purchased through DigiKey. I am trying to connect it to hello.nrfcloud but I keep getting the following message: " The fingerprint...
With reference to the Thingy:91x reference design, I see that the LNA (SKY65943-11) on the GPS signal path is powered by one of the switching converters from the nPM1300:...
Hi,
I'm using cdc_acm to create two COM ports on a PC -
// USB support
& zephyr_udc0 {
cdc_acm_uart0: cdc_acm_uart0 {

We are wondering how nrf9160 modem decides which band to use when there are multiple bands available (LTE CAT NB) and there isn't any apllied band lock from the software side...
I've been working with the nRF52840 WLCSP package for a month or two now, and in many ways it's a great compact chip. However, as my projects require more and more pins, I...
Hi guys, Im now developing my custom board with nRF52832 based on the reference schematic below. And using Keil uvision for a programming my board.
The final objective of...
Hi
I have two custom build boards based on nRF9160-SICA. Both boards also have a nrf52840 running application code. The nr91's are running identical firmware (slightly modified...
Dear.
Now Im testing the nRF24L01 to develop a module.
Using this, I want to know the receive power.
nRF24L01 has a registef to use similar function. Register...
Hi,
I'm trying to write firmware for the nrf52840 that reads from a sensor and then sends data to a PC over BLE. Ultimately, I need the BLE link to achieve ~ 1.1 Mbps throughput...
Hi all,
I observe a connection supervision timeout (HMI error code 0x08) in my Nordic firmware with certain Android smartphones (controller).
Additional info regarding...
Hi. I'm just wondering if Nordic Semi engineers have done any tests with standard beacons (any particular beacon interval and test condition) application and compared current...
Hi teams,
We made BLE mesh custom boards based on nRF52833.
These nodes are configured to send broadcast messages for every 10 seconds.
Currently, these boards uses...
Hi Sir,
We would like to use the Radio test to do the basick TX/RX test in SDK 15.2
We use the nRF52840-DK for test and follow the CLI document .
1. We use two board...
Baud rate 460800, error code NRFX_ERROR_INTERNAL(1) occurred when the serial port received data。
I want to know how to avoid this problem, the current transfer rate is less...
Hi
We need the recv() be blocking until the full amount of requested data can be returned or the operation was timeout, how to achieve this?
I tried flag MSG_WAITALL but...
Hi. Can anyone think of a way to use the nRF52832 (probably Timer) to detect approximately 125KHz-150KHz variable square wave down to about a 1Hz resolution? I'd like to detect...
Is there any example for Directed Advertising? I'll design my NUS central and peripheral use Directed Advertising, because I would like to have other bluetooth devices connected...
